Check for outdated SSL3 protocol
If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.
|Result positive||Outdated protocol version SSL3 not supported.|
|Result negativ||Outdated protocol version SSL3 supported.|
|Description||The server supports the outdated protocol version SSL3, which is considered to be highly insecure. By using this version, you massively compromise the security of the server and possibly your entire company network.|
|Background||SSL (Secure Sockets Layer) stands for a hybrid encryption protocol for secure data transmission on the internet, it forms the basis for secure connections via HTTPS. The version SSL3 was first introduced in 1995 and is no longer supported officially since 2015. The name SSL has been replaced by TLS (Transport Layer Security. The SSL3 security flaw became known through POODLE, which allows third parties to intercept private data from clients and servers via encrypted connections (man-in-the-middle-attacks).|
|Consequence||SSL3 is not supported any more by most internet browsers. Most browsers are configured to warn users against visiting SSL3 websites, or even to block access to them completely. The warning message that your visitors receive will have a negative effect on your company's presentation on the internet. If internet browsers do not trust your website, why should your customers trust you? The further use of SSL3 will also have a negative effect on search engine rank, and visitors will be alerted in the search results that there is a security issue on your website.|
|Solution/Tips||If Outdated protocol version SSL3 supported was reported: TLS encoding is considered to be the standard today. Therefore you should not use SSL3.|
